SCREEN GUIDING wnwow FRAME Filed Dec. 28, 1927 '2 ,w (Am m Patented Aug. 12, 1930 UNETED TATES AINSLEY J'. VINCENT, OF LAWRENCE, MASSACHUSETTS SCREEN-GUIDING WINDOW FRAME Application filed December 28, 1927. Serial No. 243,078.

This invention relates to a window-frame, adapted to hold and guide vertical sashes and a vertical window screen, which is movable in close proximity to the upper sash,

-' the frame including outside and inside vertical casing members and an intermediate vertical pulley stile, joined to and connecting said members, the stile and the outside and inside members forming a vertical well in which the usual sash weights, supported by cords trained over pulleys on the pulley stile, are movable.

The inner edge portion of the outside member projects across the sash-guiding inner face of the stile, and cooperates therewith in guiding the upper sash. In screened windows the inner edge of the outside member is usually provided with a longitudinal vertical tongue, adapted to enter a groove in a screen frame and guide the screen in its vertical movements.

Heretofore the tongue or screen guide has been'a strip formed separately from the outside member and attached to the inner edge thereof by small nails or brads.

Among the objections to a separately formed screen-guide strip are the following:

The strip is necessarily narrow, and when made of wood, as is usually the case, is liable to be split by the attaching nails, and the nails are liable to be crippled in driving, so that they form projections liable to scratch the surface of the groove in the screen frame and impede the movements of the screen.

The workman is liable to improperly locate the strip in nailing it to the outside member, so it may be either too near the path of the upper sash and cause binding of the screen frame thereon, or too far from said path and form a crevice through which insects may enter. A careless workman may cut the strip too short, so that a space through which insects may enter is formed at one or both ends of the strip,

I have previously devised an improved window-frame overcoming the above mentioned objections. Said frame is disclosed by my patentfor improvement in screenguiding window frames, No. 1,656,405, dated January 17, 1928. The frame thus disclosed includes outside and inside casing members, and an intermediate pulley stile joined to and connecting said members, the inner edge portion of the outside member projecting beyond the sash-guiding inner face of the stile, to cooperate therewith in guiding a sash, and having longitudinal rabbets formed therein at opposite sides of the longitudinal center of said edge, whereby said outside casing member is provided on its inner edge with an integral longitudinal tongue, constituting a screen guide, coextensive in length with the casing member and having a predetermined location thereon.

As stated by the specification of said patent, although the screen guide thus provided is not open to the objections applying to a screen guide separately formed and nailed to the outside member, it involves an increase in the original width of said member, said increase being necessary to permit the cutting of the above-mentioned rabbets, so that the cost of the member is somewhat increased.

The object of my invention is to provide a screen-guide which is integral with the outside casing member, has all of the advantages of my patented outside member, is less liable to accidental breakage, and does not involve an increase of the usual width of said outside member.

I attain this object by cutting away some of the material of the inner edge portions of each of the outside casing members, during the operation of making the same, and before they are incorporated into the frame, to form longitudinal grooves constituting screen guides integral with the outside members, coextensive therewith in length and having a redetermined location thereon, the form and arrangement of said grooves being such that a screen having projecting runner portions complemental to and interengaged with the grooves, is movable in a path predetermined by the location of the grooves, the sides of the groove in each member being spaced from the inner and outer side of the member by two parallel tongues integral with the member, each tongue protecting the other against accidental breakage.

Of the accompanying drawings forming a part of this specification,-

Figure 1 shows in perspective a portion of a window-frame, including one of the two outside casing members, said members being provided with an integral screen guide in accordance with my invention.

Figure 2 is a fragmentary horizontal section, showing portions of two outside casing members, each having an integral screen guide, portions of the two pulley stiles, portions of an upper sash, and portions of a screen frame engaged with the guides.

Figure 3 is a fragmentary view, showing portions of one edge of the screen frame shown by Figure 2.

Figure 4 is a section on line 4- 1 of Figure 3.

The same reference characters indicate the same parts in all of the figures.

Figure 1 shows a portion of one of the upright sides of a window casing, the opposite side being similarly constructed. 12 designates the inside vertical casing member, 13 the outside vertical casing member, and 14 the pulley stile, the upper portion of which supports the pulleys 011 which are trained the sash cords supporting the usual sash weights movable in the vertical well formed by the members 12 and 13 and the stile 14. The stile is joined to and connects the members 12 and 13, as usual. 15 designates a ortion of the stool or sill member of the easmg, joined as usual to the lower ends of the casing members and stile. The inner edge portions of the outside member 13, projects across the sash-guiding inner of the stile to cooperate with the stile and the usual parting bead 16 in guiding the upper sash 17. The lower sash (not shown) is guided by the stile, the parting bead and the inside stop bend 18, as usual.

In carrying out my invention, I cut in the inner edge of each of the members 13, before said members are incorporated in the casing, a longitudinal groove 19, located midway between the outer and inner sides of the member. The grooves may be cut quickly and accurately by cutters of a wood-working machine, known as a straight molder, and may be formed by the same operation which forms, in the inner side of the member 13, the usual groove 21 which receives the tongue 20 on the outer edge of the stile 14:.

The faces of the grooves 19 are integral with the members 13, and collectively constitute guides for a screen frame 23.

The screen-guiding sides of the grooves 19 are spaced from the inner and outer sides of the members 13 by parallel tongues 22 integral with said members, there being two of said tongues located side by side on each member. Each tongue is adapted to protect the other against accidental breakage. For example, if crushing pressure is accidentally exerted simultaneously on the outer faces of the two tongues, some of the pressure is sustained by one tongue, and some by the other, so that liability of serious injury to either tongue is less than would be the case if there were only one tongue constituting the screen guiding rib disclosed by my former patent.

The upright members of the screen frame are provided with projecting runners complemental to and interengaged with the guides formed by the grooves 19, said runners being adapted to permit a separable interengagement between the screen and the guides.

The runner at one vertical edge may be composed of spaced apart rib sections 25, formed to enter and slide in the groove 19, in one of the outside members, and studs 26, slid'able in sleeves or sockets 27, fixed in orifices formed for their reception in the screen frame and normally projected by springs 28, the rib sections 25 being spaced apart, and the studs 26 located between the adjacent ends of the rib sections, and normally projected therefrom into a groove 19, as indicated by Figure 4. There may be two studs 26, each located a few inches from an end of one of the vertical dges of the screen.

The runner at the opposite vertical edge of the screen frame may be composed of a rib 29, formed integral with or fixed to the frame and slidable in the opposite groove 19. The arrangement shown is such that when the runners are engaged with the groove 19, the screen may be removed, by first forcing it edgewise to the right, as viewed in Figure 2, the studs 26 yielding until the rib 29 is withdrawn-from the corresponding groove 19, so that the screen-frame may be swung outward.

WVhen the screen is in use, the rib sections 25 and studs 26 close the space between one vertical edge of the screen-frame, and the adjacent outside member 13, and the rib 29 closes the space between the other vertical edge and outside member.

It will be seen that the longitudinal screen guides, formed by the grooves 19, are integral with outside members 13, are coextensive in length with said members, and have a predetermined location thereon, the form and arrangement of said guides being such that a screen having projecting runner portions complemental to and interengaged with the guides, is guided thereby in a path predetermined by the location of the guides.

No increase of the usual width of the mem bers 13 is required, so that the cost of said members is not increased. The reason for this is found in the fact that the screen is guided by side faces of a groove formed wholly within the inner edge of a member 13 of the usual width. In the frame of my former patent the screen is guided by the sides of a rib projecting from the inner edge of said member, so that the width of the member must be greater than the usual width to provide the material from which the rib is formed.

I claim:

In a window frame which includes elongated vertical outside and inside casing members and intermediate sash-guiding stiles, the inner edge portions of the outside members projecting from the sash-guiding faces of the stiles to cooperate therewith in guiding a sash and having screen-guiding means integral within said inner edge portions, said means being provided by forming longitudinal grooves in the inner edge faces of the outside members, said grooves extending from end to end of the outside members, the sides of said grooves forming screen-guiding faces backed by parallel tongues integral with the outside members, said screen-guiding faces being within the inner edge faces in which said grooves are formed, so that the width of the outside members is not increased by the screen-guiding means, each of said tongues protecting the other, so that liability of breakage of the integral screen-guiding means is reduced.

In testimony whereof I have aflixed my signature.
